为提高深远海网箱应对极端天气的能力 ,依据规范要求对某深远海网箱进行了压载水系统设计 ,并在养殖海域进行了网箱沉浮试验 ,试验过程中采用倾角传感器与液位遥测换算两种方法记录网箱倾角 。结果显示 : 网箱沉浮时间约 6h,满足设计要求;网箱沉浮速度与网箱截面积负相关 ,在截面突变处沉浮速度变化明显;网箱横纵倾测量最大值分别为-2. 5°和 1. 25° ,网箱横纵倾计算最大值分别为-1°和 1° ;沉浮试验中网箱倾角测量值与计算值的变化趋势一致性良好 。通过沉浮试验验证了压载水系统的合理性 ,倾角传感器敏感程度更高 ,可用于网箱倾斜报警 。双监测方案为深远海网箱的优化设计提供了高精度数据支持。

To enhance the cage’s resistance to extreme sea conditions,a ballast water system was designed in compliance with regulatory requirements,and buoyancy tests were conducted at the farming site. During the trials,two methods -inclination sensor and liquid level telemetry conversion-were employed to monitor the cage ’s inclination. The results demonstrated that : The cage’s buoyancy process lasted approximately 6 hours, meeting design specifications; Buoyancy speed exhibited a negative correlation with the cage’s cross-sectional area,with pronounced velocity fluctuations observed at sectional transition points; The maximum measured horizontal/longitudinal angles reached -2. 5° and 1. 25° respectively,while calculated values peaked at -1° and 1° ; The inclination data from both measurement methods showed consistent trends throughout the test. The ballast water system's performance was confirmed via buoyancy testing,where the inclinometer's enhanced sensitivity facilitated real-time net cage tilt detection. The dual-monitoring approach provided high-precision data for the optimization design of deep-sea cages.
